To all whom it may concern: 7

Be it known that I, "CHARLES FREDERIK VILHELM FLINT, a subject ofthe King' of Denmark, residing at, Copenhagen, Den mark, have invented a new and useful Improvement in Machines forMaking I-Iorseshoes; and I do hereby declare the following to be a-full, clear, and exact description 'ofthe same. a

The invention relates to a machine for making horse-shoes the characterstic 1n which consists'in the rod-shaped bodyyo'f which the horse-shoe is made being retained at one and the same working. place whilethe bending and the operations necessary a for the making of the calks and the clipping are carried out, the making can be effected exceedingly quickly so that the machine is. excellently adapted for manufacturing: .in great quantities.

In the drawing is shown an embodiment of the invention.

Figure -1-sh'ows a side-view of chine partly in-section, or

A 'Fig. 2' a top-view of the same, certain parts being broken awayand Fig. 3 a detail.

The machine frame 1 carries a thickplate 3 secured by means of bolts 2. v In the mag chine frame is journaleda driving shafti' provided with idle and fixed pulleysynot shown, which through a gearing 5, 6 drives the main shaft? of the machine; OnI-the plate 3 are secured two heavy pillars 8,' at

top carrying bearings 9 fora shaft-10.';-

About in the middle of the pillars ,8fis secured a guiding member 11 for the membersmentioned below serving for bending. the

calks on the horse-shoe'and retaining'the'. same during the variousoperations This guiding member 11 is shown separately in Fi 3. A

. 6n the plate 3 right betweenvthe pillars: 8

is secured ananvil .12 having agraised part 13 the shape of whichlcorrespondswto,the, inner side ofla horse-shoe.1 This part 113 has aplane uppersurfacen Above theanvil.

is-arranged an upwardand downward Smov: able pressing rod 14 carrying a'plate' la with-a plane undersur-face. r Asishown in= Fig. 2 this plate 15 has a shape correspond ing to the outer curved surface of'a'horse shoe. When the plate 15'rests against the f raised part 13, an outwardly open horseshoe shaped channel is formed aroundsaid cause-the body to bepr'essedrightinto the :said channelthejsides of theyjaws 16, 16 facing eachotherhave ashape correspond .ingto the outer side of a horseshoe. Closer to be produced, Willi extend beyond the vertical edges of the anvil12. -While the body ,Jis still retained by the press foot 14, 15 a "1011520 descends and jbends the ends of the body thus producing the c'alksv of the horse I shoe. This zroll 20 is journaled' on a rod 21' which i is guided vertically in the guiding member 11, and the roll has I two conical surfaces 22,22, pressing against the ends of the body. When the cal-ksare produced the I :roll20 immediatelyifisraised again.- Con-, T temporaneously :with the bending ofthe calks e 1 the clipping ismade on the front" surface of the horse-shoe. In the machine shown this is effected bya roll 23 beingpressed against part. In producing a-horse-shoe the red hot body-18 Swhich: is beforehand rolled and which is showninFig. 2 in dotted lines, is

by. means. of a pairof tongs arranged on the-anvil 12, whereafter the presser-foot 14,

t'urnable onpivots 17 swing forward and under and upper surfaces. In order/t0 toflthe pivots .17, 17f the jaws are further" shaped in such a (manner that the touching The ends of the body, ofv which 'calks are the body from below and owing to its special shape, vide Fig.*2, presses up the bod into a .-clipping..;The roll 23 thenimmediately y descends again. 1': e a so 1.;When these 1 operations are carried out and the, jaws 16,16 have been swung back, 1 0 ithe press .foot is lifted and the produced, horse-shoeremoved, whereupon a new body 7 is*placedfon the anvil. r The horse-shoe isinj known manner provided with nail-groove 15 passesdown and retains the middlemost 7 part of the body. Thereafter two jaws 16 a 7 5 pointsbetween'the jaws and the body move fromthe middle of the same toward itsends when the body is pressedinto-the channel.

.24 connected with a forward and backward 30 is adjustable by means of a sleeve 33 to are produced by the rolls 20 and 23, respectively, and thatthe body is retained by the press foot '14, 15.

These members can be driven in any suitable manner desired so as to carry out their operations at the right moments. As regards the shown embodiment the moving mechanisms of these members will be explained below.

The jaws 16 are through connecting rods movable head 25 to which are secured two rods 26 sliding in a guide 27 on the plate 3. The head 25 is through a link 28 connected with ,the uppermost end ofv a two-armed lever 29, pivoted on the frame 1, the lower end of which lever by means of a connecting rod 30 is connected with the crank-pin 31 of a double crank 32 secured to the main shaft 7. The length of the connecting rod lution of the shaft 7.

' The roll 23 is journaled in a fork38 on a 'rod 39 guided in the plate 3, the lower end of which rod carrying two rolls 40, one of which only is seen in Fig. 1. These rolls-40 are by a spring 41 arranged around the rod 39 pressed against one of the crank arms of the double crank 32, said arm serving as a cam, shaped in such a manner that the first part of the upward motion of the roll 23 is effected quickly, whereas thelast part of the motion during which the roll presses 1 against the body and produces the clipping,

is'slow. The lateral pressure influencing the roll 23 is received by two brackets .42 secured to the plate3, on the vertical sides of which slides the fork 38.

The press foot 14, 15 is actuated by a spring 43 keeping a roll 44 on'the end of the rod 14 pressed against the circumference of the cam member 47 which has such a shape so as to keep the pressfoot in itslow'ermost position while the roll 20 moves downward for bending the calks on the horse-shoe.

' The machine can work continually as well as intermittently,

Having thus fully described my invention I claim as new and desire to secure by Letters Patent:

1. A machine for making horse-shoes,

' comprising means for bending a rod-shaped body into the shape of a horse-shoe, means for the producing of calks atthe ends of said body, means for the producing of a clipping substantially at the middle of said body, and means for retaining the rodshaped'body in one and the same working place while being bent and operated upon for the producing of the said calks and clipping.

2.'A machine for making horse-shoes, comprising means for bending a rod-shaped body into the shape of a horse-shoe, retaining means for holding the bent body, a re ciprocating member adapted to produce calks on the body while being thus held, a second reciprocating member adapted to produce a clipping on the said bent body while being held by the said retaining means, the active strokes of said reciprocating members being performed simultane- -ously.

V 3. A machine for making horse-shoes,

comprising an anvil having a raised part the.

peripheral contour of which substantially corresponds to the inner side of a horseshoe, whereby an outwardly open horse-shoe shaped recess is formed around said raised part, a reciprocating press-foot adapted to bear against the upper surface of the raised part, means including a pair of reciprocating pivoted jaws for pressing a rodshaped body into the said recess around the raised part of the anvil, a reciprocating member adapted to engage the ends of the said body while being held firmly between the press-foot and thereby forming calks, and another reciprocating member adapted to produce a clipping onthe body while'the latter is held between the press-foot and the anvil.

4. A machine for making horse-shoes, comprising an anvil, a reciprocating pressfoot adapted to coact with the said anvil for holding a rod-shaped body between. them, means including a pair of reciprocating pivoted jaws for bending the said body into the shape of a horse-shoe,a reciprocating roller having two conical surfaces adapted to produce calks at the bent horse-shoe shaped body while being held between saidanvil and press-foot,zand a second reciprocating roller adapted to produce a clipping on the bent body while being held in thesaidmanher, said rollers being adapted to be moved against the bent body from opposite sides.

In testimony whereof I have aflined my signature in presence of two witnesses.
